The Rhino R24FXX-EC is the first analog card for Asterisk that eliminates "bit-banging" the PCI bus. Other manufacturers have been known to have problems with bit-banging. The R24FXX-EC has built in echo cancellation so there is no need to purchase a separate module. The Rhino R24FXX-EC PCI analog card features a control element to remove all "bit banging" on the PCI bus, something that other manufacturer's have yet to solve! This Rhino feature significantly reduces PCI and CPU overhead.

Rhino's onboard echo-cancellation provides excellent voice quality and fast convergence rate. There is no divergence due to doubletalk and cancels multiple independent tails. The Tone Disabler disables echo canceller during voiceband modem and FAX connections. The echo cancellation module is a G.168 compliant line echo canceller, which meets and exceeds G.168-2002
